Diane von Furstenberg got political during Fashion’s Night Out on Thursday. The iconic designer got on the mike at her Meatpacking District store, and instead of talking fashion, she talked politics. She told the crowd, “Everyone here better be a Democrat; no Republicans” and went on to say, “Make sure you go home and watch the president at 10 p.m.” As she hustled out the door, she told one fashionista, “I just want to leave and watch the president talk.” Things were a little wilder over at Donna Karan’s store on 61st and Madison, where police arrived to manage the crowds as Patrick McMullan hosted a party for his FDNY calendar. Twelve of NYC’s hottest firemen strutted their stuff and posed with fans. We’re told a police car, with its blue lights flashing, was stationed outside the store to keep in line the women who were nearly rioting to get close to the hunky hosemen. Over at Saks, Amar’e Stoudemire was surrounded by fans as he signed copies of his children’s book, and was seen hugging Anna Wintour.
